Choosing the right mattress for your body is one of the easiest ways to soothe this pain. Sleeping on a mattress not suited to your body can reinforce unnatural spinal alignment causing poor posture, straining muscles and pressure points. While you sleep your ligaments, spine and muscles should completely relax and restore themselves. During this important time your spine should be in neutral alignment, meaning your spine is level and doesn’t unnaturally curve too much. It is also key that your whole body is supported rather than your weight pooling on specific points like your hip and shoulder joints. Therefore it goes without saying, your sleeping positions affect your back pain too.
